tti 2.5 x system on 72 demon 340 review

well first off i will say i had these installed rather than try to do it myself. i am glad i did. the drivers side lead pipe that comes off the manifold fits great , but not without it's problems. the pipe is too close to the transmission kickdown linkage. it will need to be bent out away alittle more from it to clear. no problems on the torsion bar clearance.the exhaust guy that did the install said the drivers side was pretty hard to install. original starter works, but will have to be dropped down for the install. the passenger side lead pipe that they sent was fine , execpt the end was not flared enough to fit the manifold.it had to be cut off and new piece added to fit the flare. past the engine the system was made correct. the only other problem was the hangers at the end of the tailpipe. the tailpipes have built in hangers on them that are further back than the factory hangers for the chrome tips. this is not a problem if you don't plan to use the factory style chrome tips. if you do you will have to cut the pipes back enough to allow you to use the factory chrome tips. now the sound is another story. i used the dyomax superturbos that come with the system, they sound really nice at idle. at speed from 15-40 mph they are almost too loud inside the car! really, conversation is diffucult, and i don't think you could hear a radio without turning it up! i only have the factory sound deading that came in the car, so i can change this with some additional sound deading material. i am just letting you know what you are in for here. performance from factory style 2 inch ,no crossover style duals to this new system is very noticable. the x system definatly helps with performance. honestly the feeling was almost like a gain i would have expected from a header install. i would imagine this system would really show it's capabilities with a set of tti headers. overall i highly recommend this system. :thumblef:
